BEARING.

I '0 all whom it may concern:

,3 invented certain new and useful Improvements in Bearings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to means for properly spacing several rotors on a single shaft and has for an object to provide means for accurately and positively securing several independent rotors upon-a shaft without contact or friction against one another.

Another object is to prov de means for mounting-several wheels as in a turbine so that each Wheel is in its proper place and no movement along said shaft is possible as resultant from wear or improperly.assembling.

()ther objects'will be apparent from the following specification, appended claim and drawings in which Figurel is a sectional'view of my construction. Fig. 2 is a section transversely through the shaft showing one of the wheels in elevation. I

In the construction of turbines, pumps and the like it is frequently necessary that several wheels be'mounted upon the same shaft and that said wheels assume the proper position thereon. In setting up a device where the hubs bear against one another and the end hubs bear againt a fixed collar, any displacement of one wheel will throw the others out of 'alinement' so in order to avoid such a contingency I provide a shaft 10 with annular grooves 11 Specification of Letters Patent.

i which are spaced at proper intervals. Split i rings comprising the members 12 and 13 are adaptedto fit in said grooves and in building upea unit, a Wheel 14 is mounted on the shaft and the hub 15 is cut out at 16 to form a flange 17 which envelope the members 12 and 13 to prevent displacement, then the secondpair of members 12 and 13 are placed in position and the second wheel applied. This method of building up a unit may be repeated until the desired size and proportions are obtained.

'The operation of the device is obvious from the foregoing and claim In a device of the class described, a shaft having annular grooves formed thereon, a plurality of Wheels each having hubs with one face plane and disposed at an angle with the wall of the bore of the hub, the opposite face provided with a bore concentric with the bore of the hub proper, and of greater diameter, forming a shoulder adapted to coincide with one of the walls of a given groove, the other wall of said groove being in line with the adjacent face of the hub said face being adapted to abut the opposite face of an adjacent hub and form an annular inclosed chamber between each two hubs, and an annular member within the chamber engaging the shaftand resting against the plane face of one hub and disposed within the larger bore.

In testimony whereof I atfix my signature in presence-of two witnesses.
